Machine for development and deployment of analytical models

ABSTRACT

A machine provides a system and interface to allow domain experts and other users to develop, deploy, and iterate on analytical models. The system facilitates building, deploying, and/or training analytical models, by, e.g., exposing analytical model configuration parameters to a user while abstracting model building and model deployment activities. The system can also determine resource loads or execution times for various analytical models and can schedule model execution accordingly. The system also provides a dynamically reconfigurable user interface for controlling the system.

TECHNICAL FIELD

This disclosure relates to machines and complex system architectures forbuilding and/or deploying analytical models.

BACKGROUND

The field of data science, and more particularly, the development andimplementation of analytical models, has typically required strongcomputer and processing system skills and familiarity with data science.These specialized skills were needed to develop, setup, and programmodel algorithms and to access and prepare data so that the data waseffective for training the model, and so that running the model on thedata would give meaningful results. These complex technical challengeshave traditionally left scientists and engineers with the daunting taskof building and implementing analytical models that are useful in theirengineering and scientific fields. That is, analytical modeling istypically a field in which scientists and engineers have lessfamiliarity, and which in any event is tangential to their primary goalof extracting insights from data.

Additionally, creating accurate analytical models is often anexperimental process requiring multiple iterative cycles of hypothesistesting. The iterative cycles can each take significant time to setupand/or complete (e.g., days or months). The extended creation, setup,and/or training process hinders development of additional analyticalmodels and analytical models of higher accuracy.

DETAILED DESCRIPTION

Analytical models, also called predictive models, are a form ofmathematical model that defines and describes relationships amongvariables in a data set. An analytical model may include an equation anda set of coefficients which, together, map an arbitrary number of inputvariables to an output, typically a single output. This output can beused to provide predictive results for a given set of inputs. Forexample, an analytical model may receive inputs of a future date and thecurrent temperature, and may provide an output predicting the chance ofrain on that future date. Analytical models can also provide informationon events, occurrences, or transactions that have already occurred. Forexample, analytical models can be used to determine whether a recordedtransaction was fraudulent.

Analytical models may take many different forms, including machinelearning models or equations. Machine learning models are abstractionsof machine learning approaches. Example machine learning approachesinclude linear regression, decision trees, logistic regression, Probitregression, time series, multivariate adaptive regression splines,neural networks, Multilayer Perceptron (MLP), radial basis functions,support vector machines, Naïve Bayes, and Geospatial predictivemodeling, to name a few. The machine learning model can be trained on aset of training data. The training results in an equation and a set ofcoefficients which map a number of input variables to an output,typically a single output. In the model, coefficients of the equationscan often be parameterized as:

$y = {\sum\limits_{j = 1}^{N}\;\left( {a_{j}x_{j}} \right)}$where a_(j) is a coefficient and x_(j) is an input and y is thepredicted output. In essence, both the machine learning model and theequation are subclasses of a higher order class referred to as a model.

The possible number and diversity of applications for analyticalmodeling is essentially limitless. However, a technical challenge existsin that the development and implementation of analytical models requiresextensive experience in data science and/or data engineering. Forexample, development and implementation of an analytical model mayrequire extensive computer programming abilities to properly configureand run the analytical model, which is a skill typically associated witha data engineer. Further, given the overhead cost and time to developand implement an analytical model, in order to reduce the number ofiterations, a data scientist is often required to select the bestanalytical model type and provide the best configurations of that modelbased on their extensive understandings of mathematical modeling and themodel types involved.

A third player, the domain expert, may provide the most insight intocreating accurate analytical models. A domain expert has extensiveexperience or knowledge about the subject matter that is the focus of aparticular analytical model. The domain expert may be best suited toanalyze a particular set of data or a particular subject given theirexperience, wisdom, or intuition in that subject to help create andoptimize a particular analytical model. However, as discussed above,domain experts may not have the requisite data science and/or dataengineering understanding required to successfully and efficientlyimplement an analytical model. For example, a meteorologist may be bestsuited to analyze a data set relating to weather changes to create anaccurate analytical model. However, that meteorologist may not be versedin data science so as to be able to initially select the best model typeand coefficients that result in the lowest number of model testingiterations during development of that model. Thus, the meteorologist mayrequire more model alteration and testing iterations to fine tune ananalytical model. Moreover, the meteorologist may not have any computerprogramming experience or programming knowhow required to create,implement or run the analytical model, which would otherwise require theservices of an experienced data engineer.

Thus a technical challenge exists in exposing the development andimplementation of analytical models to domain experts in a way thatallows domain experts to quickly, easily, and iteratively develop, test,and implement analytical models. These technical challenges faced by thedomain expert may be prove prohibitive to the development andimplementation of analytical models in many instances. Additionally,data scientist and data engineers face similar technical challenges ofquickly and efficiently developing, testing, and implementing analyticalmodels.

The system architecture for machine learning described below implementstechnical solutions to these and other technical challenges. FIG. 1shows an example machine 100 for implementing machine learning. Themachine 100 includes model builder circuitry 102 and model deploymentcircuitry 104. The machine 100 also includes a model storage database106, a results storage database 108, and an application programminginterface (API) 110, which may define functional access (e.g., throughfunction calls) to a model metadata storage database 112 as well themodel builder circuitry 102, the model deployment circuitry 104, theresults storage database 108, the resource allocation circuitry 116,and/or other elements of the machine 100. The machine 100 furtherincludes user interface circuitry 114 and resource allocation circuitry116. The machine 100 may further include or be coupled to a computeengine 118, an online message queue 120, and/or an historical datastorage database 122.

The various components and circuitry of the machine 100 areinterconnected, for example, by one or more system busses 215 ofcommunication interfaces 208 (see FIG. 2). The system busses 215 may beconfigured to enable intercommunication between the model buildercircuitry 102, the model deployment circuitry, 104, the user interfacecircuitry 114, the resource allocation circuitry 116, the compute engine118, the model storage database 106, and/or the results storage database108 when such elements are collocated within a single machine 100 or acluster of closely networked machines. If such elements are distributedacross one or more separate computers or server forming parts of themachine 100, intercommunication between the elements may be effectedthrough wired communication circuitry 214 and/or wireless communicationcircuitry 210 (see FIG. 2). The communication interfaces 208, andparticularly the wireless communication circuitry 210 or wiredcommunication circuitry 214, may also be connected to a network 216 (seeFIG. 2) such as the Internet or another intranet. By and through thecommunication interfaces 208 or other communication connections, themodel builder circuitry 102 can communicate with the user interfacecircuitry 114, the model storage database 106, the results storagedatabase 108, and/or the compute engine 118. By and through thecommunication interfaces 208 (e.g., the system busses 215, the wirelesscommunication circuitry 210, or the wired communication circuitry 214),the model deployment circuitry 104 can communicate with the userinterface circuitry 114, the model storage database 106, the resultsstorage database 108, the resource allocation circuitry 116, the onlinemessage queue 120, and/or the compute engine 118. Similarly, by andthrough the communication interfaces 208 or other communicationconnections, the resource allocation circuitry 116 can communicate withthe user interface circuitry 114, while the results storage database 108can be accessed by the user interface circuitry 114 and/or the computeengine 118 (e.g., for storage of computed or predictive results).Similarly still, by and through the communication interfaces 208 orother communication connections, the model storage database 106 can beaccessed by the compute engine 118 (e.g., for storage or recalling orstoring analytical models). Other interconnections may be possible. Forexample, the model builder circuitry 102 may be connected to thehistorical data storage database 122 to retrieve stored historical data,for example, during training of an analytical model. In someembodiments, much of the communication between the user interfacecircuity 114 and other circuitry components or databases of the machine100 may be conducted according to interface instructions or commandsspecified by the API 110.

The model builder circuitry 102 creates and develops new analyticalmodels or edits existing analytical models. The model builder circuitry102 also trains and validates new and existing analytical models withtraining data. The model builder circuitry 102 also manages the storageof trained and untrained analytical models and updates metadata relatedto those analytical models. The model builder circuitry 102 may interactwith a user via the user interface circuitry 114, for example, accordingto rules and functions defined and exposed to other entities by the API110. The model builder circuitry 102 may also interact with the computeengine 118 to train an analytical model. Further technical details ofthe model builder circuitry 102 are provided below.

The model deployment circuitry 104 deploys analytical models on thecompute engine 118, for example, to perform predictions on live incomingdata, historical data, batch data, and/or stored data. The modeldeployment circuitry 104 retrieves analytical models stored in the modelstorage database 106. The stored analytical models may have been createdby the model builder circuitry 102 in certain embodiments. The modeldeployment circuitry 104 prepares analytical model processing pipelinesto process (e.g., with the compute engine 118) incoming data (e.g.,provided via the online message queue 120) and to store results of theprocessing (e.g., in results storage database 108). Further technicaldetails of the model deployment circuitry 104 are provided below.

The resource allocation circuitry 116 determines resource loads foranalytical models and determines resource load capabilities of a computeengine 118 or other resources. In so doing, the resource allocationcircuitry 116 can determine a maximum execution frequency for ananalytical model on the compute engine 118. The resource allocationcircuitry 116 can also schedule execution of an analytical model by thecompute engine 118 according to the maximum execution frequency and/orother factors, rules, and considerations. Further technical details ofthe resource allocation circuitry 116 are provided below.

The user interface circuitry 114 provides an analytical model controluser interface to a user. The user interface circuitry 114 interactswith a user, the model builder circuity 102, and the model deploymentcircuitry 104, for example, through the API 110, to facilitate usercontrol of each of the circuitry elements. For example, the userinterface circuitry 114 allows a user to create, edit, or train ananalytical model using the model builder circuitry 102. The userinterface circuitry 114 may also allow a user to deploy or withdrawdeployment of an analytical model using the model deployment circuitry104, or to setup or edit a processing pipeline for the analytical modelusing the model deployment circuitry 104. The user interface mayimplement a dynamically reconfigurable graphical user interface (GUI).Further technical details of the user interface circuitry 114 areprovided below.

FIG. 2 shows an example specific system implementation 200 for themachine 100 described above. According to the system implementation 200,the machine 100 includes system circuitry 202 to support implementationof the various circuitry elements and functionality discussed above withrespect to FIG. 1 and elsewhere. In one embodiment, the system circuity202 includes processors 204, memory 206, and/or other circuitry. Theprocessors 204 may be connected to the memory 206 and may comprise amemory system including a plurality of memory devices collocated ordistributed across multiple systems. The memory 206 may store controlinstructions, operational parameters for the control instructions,datasets, and other information. The control instructions may beexecuted by the processor 204 to implement any of the processingdescribed below, according to a configuration set by the operationalparameters. Further, in some embodiments, various circuitry elements ofthe machine 100 may be implemented by the system circuitry 202. Forexample, the model builder circuitry 102, model deployment circuitry104, the model storage database 106, the results storage database 108,the API 110, the model metadata storage database 112, the user interfacecircuitry 114, and/or the resource allocation circuitry 116 may beimplemented in whole or in part by one or more instances of the systemcircuitry 202.

As is shown in FIG. 3, the memory 206 may store data and instructionsfor use by the circuitry elements and/or to implement portions of thecircuitry elements. In one embodiment, the memory 206 includes modelbuilding instructions 302, which may further include model developmentinstructions 304, model training instructions 306, and model storageinstructions 308. The processor 204, memory 206, and model buildinginstructions 302 may implement portions of the model builder circuitry102 shown in FIG. 1.

The memory 206 may also include model deployment instructions 310. Theprocessor 204, memory 206, and model deployment instructions 310 mayimplement portions of the model deployment circuitry 104 shown inFIG. 1. As part of the model deployment instructions 310, the memory 206may include pre-defined analytical model compatibility requirements 311(discussed below). The memory 206 may also include model managementinstructions 312. The processor 204, memory 206, and model managementinstructions 312 may implement various portions of the model buildercircuitry 102, the model deployment circuitry 104, or other circuitryelements to provide functions relating to the management of analyticalmodels. Some of these model management functions include storing,updating, cataloging, maintaining, tracking, and versioning ofanalytical models, storing and tracking update histories for analyticalmodels or training data, scheduling deployment, un-deployment, updates,maintenance, evaluation, and re-training of analytical models, storingconnections between analytical models and training data, and storing andmaintaining status and logs for analytical models (e.g., to findexisting analytical models for future projects). The model managementinstructions 312 may implement version management features. For example,during its lifetime, an analytical model may become less accurate, atwhich point it may be retrained (e.g., to reestablish the relevant datainputs and values of the coefficients) or be decommissioned. To supportsuch model management functions, the model management instructions 312may provide instructions and logic for grouping versions of analyticalmodels and allowing comparison between the performances of the variousanalytical models. For example, versions of analytical models may begrouped according to version number, creation date, revision dates,model type, run time environment, error rate, or other sortablecharacteristics.

The memory 206 may also include compute engine interface instructions314 for interfacing with the compute engine 118. The processor 204,memory 206, and compute engine interface instructions 314 may implementor work with portions of the model builder circuitry 102 and/or themodel deployment circuitry 104 that interface with the compute engine118. For example, the compute engine 118 may be a third-party cloudcomputing service or analytics service which may utilize a particularAPI, instruction set, or other interface, with which the compute engineinterface instructions 314 may provide instructions for interaction. Inone example, the compute engine 118 includes a job server to start andstop data processing jobs via Hypertext Transfer Protocol (HTTP)instructions and the compute engine interface instructions 314 mayenable interaction therewith.

The memory 206 may include resource allocation instructions 316 whichmay further include nested therein load analysis instructions 318 andexecution scheduling instructions 320. The processor 204, memory 206,and resource allocation instructions 316 may implement portions of theresource allocation circuitry 116 shown in FIG. 1. The memory 206 mayalso include user interface instructions 322. The processor 204, memory206, and user interface instructions 322 may implement portions of theuser interface circuitry 114. The user interface instructions 322 mayinclude instructions and logic to provide or implement a dynamicallyreconfigurable GUI to a user. The memory 206 may also include APIimplementation instructions 324 which may implement the API 110.

The memory 206 may include metadata management instructions 326. Theprocessor 204, memory 206, and metadata management instructions 326 maycontrol the creation, storage, updating, and removal of metadataassociated with analytical models. The metadata management instructions326 may work in tandem with the model management instructions 312 toperform functions relating to the management of analytical models.Further, the processor 204, memory 206, and the metadata managementinstructions 326 may operate with the API implementation instructions324 or the API 110 to interface with a model metadata storage database112 and/or to enable the user interface circuitry 114 to interact withmodel metadata stored within the model metadata storage database 112 orelsewhere.

The memory 206 may also store model metadata 328. In one embodiment, themodel metadata 328 stored on the memory 206 operates as the modelmetadata storage database 112 or as another metadata store 242 shown inFIG. 2. In another example, the model metadata 328 shown in FIG. 3 maybe stored in another location, such as metadata store 242. The modelmetadata 328 may include, for example, model approach metadata 330,model parameters metadata 332, input variables metadata 334, modelstorage location metadata 336, results storage location metadata 338,error rate metadata 340, and model state metadata 342. Other types ofmodel metadata may also be stored as part of the model metadata 328 suchas, for example, analytical model subclass metadata, analytical modeltype metadata, output variables metadata, date metadata, update historymetadata, and version metadata. The model metadata 328 may be stored ina persistent cache for fast access.

Returning to FIG. 2, the system implementation 200 may also includecommunication interfaces 208, which may support wireless communicationvia wireless communication circuitry 210 and antennas 212. Examplewireless communication protocols may include Bluetooth, Wi-Fi, WLAN,near field communication protocols, cellular protocols (2G, 3G, 4G,LTE/A), and/or other wireless protocols. Also, communication interface208 may include wired communication circuitry 214. Example wiredcommunication protocols may include Ethernet, Gigabit Ethernet,asynchronous transfer mode protocols, passive and synchronous opticalnetworking protocols, Data Over Cable Service Interface Specification(DOCSIS) protocols, EPOC protocols; synchronous digital hierarchy (SDH)protocols, Multimedia over coax alliance (MoCA) protocols, digitalsubscriber line (DSL) protocols, cable communication protocols, and/orother networks and network protocols. The communication interfaces 208may be connected or configured to connect to one or more networks 216,including the Internet or an intranet, to enable the machine 100 and thesystem circuitry 202 therein to communicate with other systems anddevices. Additionally, the communication interface 208 includes systembuses 215 to effect intercommunication between various elements,components, and circuitry portions of the machine 100. Example systembus implementations include PCIe, SATA, and IDE based buses.

The communication interfaces 208 may enable interconnection of variouscircuitry components illustrated in FIG. 1 within the machine 100 (e.g.,via one or more buses, computer component interfaces, or peripheralcomponent interfaces). For example, the communication interfaces 208 maycouple to the model builder circuitry 102, the model deploymentcircuitry 104, the resource allocation circuitry 116, and the userinterface circuitry 114. Further, the communication interfaces 208 maycouple to the model metadata storage database 112, the results storagedatabase 108, and/or the model storage database 106 internally viasystem busses 215 if internally maintained, or externally via thewireless communication circuitry 210 or the wired communicationcircuitry 214 if externally maintained.

The communication interfaces 208 may support communication with datacenters 218. The data centers 218 may include data stores 220 and/orprocessing servers 222. The data centers 218 may be external orthird-party data centers 218 that are operated by a separate serviceprovider than an operator of the machine 100. Alternatively, the datacenters 218 may be directly or indirectly associated with the machine100, for example, as part of a combined or shared service operated by acommon service provider. In one embodiment, the data center 218 providesthe compute engine 118 used by the machine 100 as an analytics service,cloud computing service, or cluster computing service to provide onlineanalytical processing (OLAP) of analytical models. Examples of suchcomputing service frameworks include Spark™, Hadoop®, Apache™, Yarn, R,and OpenCV. Commercial versions of the data centers 218 may includeservices such as Amazon® Web Services, Google Cloud Compute Engine,Oracle®, and Microsoft® Azure™. In some embodiments, the data center 218is a cluster of machines that may be physical, virtual, or containerizedthat run some other framework (e.g., R or OpenCV), which may include aload balancer as a front end. By certain approaches, if the machines arecontainerized or virtualized, the containerized or virtualized machinescan be autoscaled up and down.

The data center 218 may provide data storage services. In otherembodiments, the machine 100 may be in communication via the network 216with multiple other databases, such as database 224 and database 226,which may also provide data storage services. Example data storageservices include Amazon® S3™, Google® Cloud Storage, and Windows® Azure™Storage. These external data storage services (e.g., data center 218,database 224, and/or database 226) may be utilized for the model storagedatabase 106, the results storage database 108, the model metadatastorage database 112, and/or the historical data storage database 122shown in FIG. 1.

The communication interfaces 208 may support communication with externalclient devices, such as a client computer 228 or a client mobile device230. Communication with the external client devices may be effectedthrough user interface circuitry 114 and/or with user interfaceinstructions 322. A dynamically reconfigurable GUI may be provided tothe external client devices via the networks 216 to enable interactionbetween the client devices and the machine 100.

In some embodiments, the machine 100 may itself include various I/Ointerfaces 232, for example, to enable local maintenance engineers tointeract with the machine 100. The machine 100 may also include adisplay 234 and local user interface 236 that may include humaninterface devices and/or a local graphical user interface GUI. The localGUI may be used to present a control dashboard, actionable insightsand/or other information to a maintenance engineer. The local GUI maysupport portable access, such as, via a web-based GUI, to enablemaintenance on the machine 100 or other interaction with the machine100. This local GUI may be the same as or different from the GUIdescribed elsewhere for development and deployment of analytical models.

The machine 100 may also include a hard drive 238 and/or a solid-statedrive 240 to enable local storage of system software, user interfaces,or system instructions. The machine 100 also include a metadata store242, which may be included on or separate from the hard drive 238 and/ora solid-state drive 240. The metadata store 242 may operate as the modelmetadata storage database 112 shown in FIG. 1 and/or the storagelocation for the model metadata 328 shown in FIG. 3.

FIG. 4 shows a flow diagram of logic 400 that the machine 100 mayimplement to build and/or deploy an analytical model. For instance, themodel builder circuitry 102 and/or the model deployment circuitry 104may be configured to implement some or all of the logic 400 shown inFIG. 4. The model builder circuitry 102 may be configured to receive aselection of an analytical model via the communication interface 208(402). For example, a user operating a client device (e.g., clientcomputer 228 or client mobile device 230) may make a selection of a newor existing analytical model to develop. This may entail a selection ofa particular base analytical model algorithm type upon which to base anew analytical model on, or may entail selection of an existinganalytical model previously started or developed. The model buildercircuitry 102 may be configured to receive a selection or alteration ofinputs, output, and/or parameters for the analytical model. Modelbuilding instructions 302, and particularly model developmentinstructions 304, stored in memory 206 may provide instructions andlogic to effect selection of the analytical model and the selection oralteration of the inputs, outputs, and/or parameters for the analyticalmodel.

In an alternative embodiment, the machine 100, and in particular, themodel builder circuitry 102 or the model deployment circuitry 104, mayreceive a pre-defined analytical model from any source, such as a clientdevice communicating over the communication interface 208. Thepre-defined analytical model may take, for instance, the form of ananalytical model code bundle, including code and data, that represent orencode a model of any kind. In some embodiments, the pre-definedanalytical model may also be paired with pre-computed coefficients tostart or configure the pre-defined analytical model. Theses pre-computedcoefficients are either passed to the system at the time of submissionof the pre-defined analytical or are results passed to the system fromthe running of another analytical model. These pre-computed coefficientsfor the pre-defined analytical model may have been developed orcalculated (e.g., trained), for example, using a different machine orsystem or using the same machine 100 at a different previous time. Inother embodiments, the pre-defined analytical model does not have orinclude corresponding coefficients, and the pre-defined analytical modelmay be trained to develop coefficients, as is discussed below. Thepre-defined analytical model and/or the associated coefficients may bestored in model storage database 106 as would an analytical modelcreated by the model builder circuitry 102. Other processes discussedherein with respect to an analytical model created with the modelbuilder circuitry 102 may, in many instances, be performed on thepre-defined analytical model uploaded to the machine 100. For example,deployment of the analytical model by the model deployment circuitrymay, in many instances, be the same as with a pre-defined analyticalmodel.

The model builder circuitry 102 may be configured to train theanalytical model to create a trained analytical model (404). In certainembodiments, training the analytical model (404) may be performed on thecompute engine 118 using user-designated training data. Theuser-designated training data may be provided directly by the user, maybe stored on a data store internal to the machine 100 (e.g., withinmemory 206, hard drive 238, or solid-state drive 240), or may be storedon a data store external to the machine 100 and accessible via thenetwork 216 (e.g., within data center 218, or database 224 or 226). Theuser-designated training data may be artificially generated or may beportions of actual historical data, for example, stored in historicaldata storage database 122, which portions are specified by a user.

In other embodiments, training the analytical model (404) may furtherinclude validating the trained analytical model using theuser-designated training data and determining an error rate of thetrained analytical model. Such validation may include cross-validationtechniques, including n-fold or k-fold cross-validation, or otherrotation estimation techniques or model validation techniques understoodin the art. The error rate produced may be a measure of fit. The errorrate may comprise root mean squared error, mean squared error, medianabsolute deviation error, positive predictive value error,misclassification error (e.g., for binary classifications), or otherknown measures of fit. Model building instructions 302, and particularlymodel training instructions 306, stored in memory 206 may provideinstructions and logic to effect training the analytical model and/orvalidation of the trained analytical model.

The model builder circuitry 102 may be configured to store the trainedanalytical model in the model storage database 106 (406). The instanceof the trained analytical model, including all its state information,may be stored in the model storage database 106. The model storagedatabase 106 may be implemented on a data store internal to the machine100 (e.g., within memory 206, hard drive 238, or solid-state drive 240),or may be stored on a data store external to the machine 100 andaccessible via the network 216 (e.g., within data center 218, ordatabase 224 or 226). Model building instructions 302, and particularlymodel storage instructions 308, stored in memory 206 may provideinstructions and logic to effect storage of the trained analyticalmodel.

The model builder circuitry 102 may be configured to store modelmetadata characterizing the trained analytical model in the modelstorage database 112 as model metadata 328 (408). For example, the modelmetadata may include an analytical model parameter for the trainedanalytical model, a storage location specifier for the trainedanalytical model, and/or a storage location specifier for the results ofthe generated results of the trained analytical model. A selected baseanalytical model algorithm type may be stored as model approach metadata330, while analytical model parameters and input variables may be storedas model parameters metadata 332 and input variables metadata 334,respectively. A calculated error rate can be stored as error ratemetadata 340. Metadata management instructions 326 stored on memory 206may provide instructions to effect management of the model metadata 328.From here on, the machine 100 has a reference to where the trainedanalytical model is persisted and how it can be used to make predictionson incoming data and batch data.

Once an analytical model has been trained and stored, deployment of thetrained analytical model can be achieved according to the following. Themodel deployment circuitry 104 may be configured to receive a selectionof trained analytical model (410). For example, a user may select atrained analytical model from a list or may enter an indication of aparticular trained analytical model. The model deployment circuitry 104may then be configured to retrieve the trained analytical model from themodel storage database 106 (412). In one embodiment, the modeldeployment circuitry 104 accesses the model metadata storage database112 to retrieve model metadata 328 about the selected trained analyticalmodel. The model deployment circuitry 104 may then review the modelstorage location metadata 336 to determine where the selected trainedanalytical model is stored within the model storage database 106. Othermodel metadata 328 may be useful as well such as, for example, modelparameters metadata 332 and/or input variables metadata 334.

The model deployment circuitry 104 may be configured to deploy thetrained analytical model on compute engine 118 to process incoming dataand to generate results (414). The model deployment circuitry 104 may beconfigured to store the generated results in a results storage database108 (416). In one approach, the model deployment circuitry 104 preparesa processing pipeline by coordinating with the data source (e.g., onlinemessage queue 120) to route messages including the live incoming data,which may include creating an message broker topic (e.g., for use withIBM® MQ, Apache Kafka, RabbitMQ, AMQP, AWS Kinesis, and/or Azure IoTEvent Hub) and publishing the source data to the topic and subscribingthe trained analytical model to the message broker topic. In otherembodiments, the model deployment circuitry 104 routes batch data,historical data, or data from within a table or other data format withina datastore in the system to the trained analytical model. The modeldeployment circuitry 104 further prepares the processing pipeline bycoordinating with the compute engine 118 to implement the trainedanalytical model on the live incoming data, batch data, historical data,and/or data table and by coordinating with the results storage database108 to store the generated results from the compute engine 118. In oneexample, the generated results from the compute engine 118 are writtento a log file in the results storage database 108, which is monitored bythe model deployment circuity 104. Model deployment instructions 310stored in memory 206 may provide instructions and logic to effectselecting and retrieving the trained analytical model, deploying thetrained analytical model, and storing the results. Further, modelmanagement instructions 312, compute engine interface instructions 314,and metadata management instructions 326 may provide instructions andlogic for interacting with the trained analytical model, the computeengine, and the metadata, respectively.

In certain embodiments, the API 110 may expose functions of the modelbuilder circuitry 102, the model deployment circuitry 104, and otherelements of the machine 100 to the user interface circuitry 114, theGUI, or the user to enable control of the functionality of the machine100. The API 110 may comprise a Representational State Transfer (REST)API, which may make use of standards such as HTTP, Uniform ResourceIdentifier (URI), JavaScript Object Notation (JSON), and ExtensibleMarkup Language (XML). Other API types may be possible in theimplementation of the API 110.

So configured, the machine 100 provides technical functionality andfeatures to a user such that the user can easily develop, train, andstore an analytical model, wherein the machine 100 creates a layer ofabstraction between the user and the processes to perform those actions.

The machine 100 may implement other features beyond those describedabove. In one embodiment, the machine 100 is provides resourceallocation and execution scheduling using the resource allocationcircuitry 116. One technical problem is that multiple analytical modelswill often run in parallel and thus compete for resources (e.g., CPUpower and memory space). If too many analytical models are running, orif analytical models having a large resource load are running, resourcesmay become depleted, thereby slowing or preventing the processing ofdata. One solution is to determine the resource load of an analyticalmodel, the resource load capability of the compute engine 118, and todetermine a maximum processing frequency which the compute engine 118will allow. Alternatively, the machine 100 may make recommendations asto increasing the amount of available resources in order to implementprocessing of an analytical model according to a desired frequency.

FIG. 5 shows a flow diagram of logic 500 that the machine 100 mayimplement to account for resource load in the deployment of analyticalmodels. For instance, the resource allocation circuitry 116 (coupled tothe model deployment circuitry 104) may be configured to implement someor all of the logic 500 shown in FIG. 5. The resource allocationcircuitry 116 may be configured to determine a resource load and/or anexecution time for the trained analytical model (502).

In one embodiment, job performance estimation is utilized. One solutionis to utilize performance modeling, which is a model or formula thatrelates the number of instances, types of each instance, as well asnumbers of jobs running in parallel with the job execution time. Thecreation of such a model (essentially a “model of models”), however,requires domain expertise in the area of analytical model performanceand in depth understanding of the analytical models subject to theperformance modeling. An alternative solution is to utilize machinelearning techniques where the job execution time is learned fromvariables such as the number of instances, instance type, CPU or memoryutilization on each instance, or other factors. In this approach, thejob estimating is learned automatically using historical performancedata from execution of the trained analytical model in question.However, this machine learning approach may require performance data tobe collected by running the analytical model in question multiple timeswith varying resource configurations to develop the historical data forexecution of the trained analytical model.

The resource allocation circuitry 116 may be configured to determine aresource load capability of the compute engine 118 (504). For example,the resource allocation circuitry 116 may have access to data describingthe processing and memory resources available for use by a particularuser or client. In other embodiments, the resource allocation circuitry116 may have testing models with known resource loads which it candeploy to test the available resources of the compute engine 118.

Because multiple trained analytical models may be implemented on thecompute engine 118 in parallel, the resource allocation circuitry 116may determine a resource load for a different trained analytical modeland/or an execution time for the different trained analytical model(506). This different trained analytical model may also be implementedon the compute engine 118. Again, such a determination may be made usinghistorical data for execution of the different trained analytical model.This may provide additional insight as to the current resource loadcapabilities of the compute engine 118.

The resource allocation circuitry 116 may be configured to determine anexecution frequency for the trained analytical model on the computeengine 118 based on the resource load for the trained analytical model,the execution time for the trained analytical model, and/or the resourceload capability of the compute engine 118 (508). This executionfrequency may be a maximum execution frequency for the trainedanalytical model on the compute engine 118.

Resource allocation instructions 316, and particularly load analysisinstructions 318, may include instructions and logic to perform loadanalysis on the trained analytical models as well as on the computeengine 118.

In order to prevent issues with overusing resources, the resourceallocation circuitry 116 may be configured to schedule execution of thetrained analytical model by the compute engine 118 no more frequentlythan the maximum execution frequency (510). The resource allocationcircuitry 116 may provide an indication to a user of the maximumexecution frequency. Alternatively or additionally, the resourceallocation circuitry 116 may provide notification to the user thatimplementation of the trained analytical model on the compute engine 118will exceed the available resources and may provide suggestions foralterations, including increasing the available resources at the computeengine 118 or reducing the load by the trained analytical model oranother implemented trained analytical model on the compute engine 118.

FIG. 6 shows a flow diagram of logic 600 that the machine 100 mayimplement to provide a user interface to a user. For instance, the userinterface circuitry 114 may be configured to provide an analytical modelcontrol user interface via the communication interfaces 208 to a user(602). In one embodiment, the analytical model control user interface isprovided as a dynamically reconfigurable GUI, which may be provided viathe networks 216 to a client computer 228, a client mobile device 230,or another device. The user interface instructions 322 stored on memory206 may provide instructions and logic for the provision of the userinterface circuitry 114 and/or the GUI.

In one embodiment, the following interactions may be provided throughthe analytical model control user interface. The user interfacecircuitry 114 may be configured to interact with the user to create ananalytical model (604). For example, the analytical model control userinterface may interact with the user to receive a command to create anew analytical model. The user interface circuitry 114 may be configuredto accept a user selection of an analytical model algorithm type for theanalytical model (606). For example, a user may select via theanalytical model control user interface a particular base analyticalmodel algorithm type that is available or provided by a particularcompute engine 118 (e.g., linear regression, logistic regression,generalized linear models, neural network, or other analytical modeltypes) for the new analytical model. Further, the user may change thebase analytical model algorithm type for an existing analytical model.

The user interface circuitry 114 may be configured to accept a userselection of an analytical model input for the analytical model (608).For example, the analytical model control user interface may receivefrom the user a selection of one or more inputs for the new analyticalmodel or an existing analytical model. Inputs may be any input that cansuitably be fed into an analytical model (e.g., today's averagetemperature, time series data of the flow rate or the pressure of waterin a water main, or transactional data for credit transactions).Typically the inputs are expressed in numerical values or a binarystates (e.g., true or false).

The user interface circuitry 114 may be configured to accept a useralteration input that is applicable to an analytical model parameter forthe new or existing analytical model (610). For example, the analyticalmodel control user interface may receive from the user an alteration ofa configuration parameter for the analytical model. Exampleconfiguration parameters include maximum number of iterations,convergence parameters, elastic or regularization parameters, and fit tointercept parameters. The applicable analytical model configurationparameters may vary with each different base analytical model algorithmtype.

In another embodiment, the user interface circuitry 114 may receive auser-created pre-defined analytical model created outside the machine100 or at a previous time by the machine 100. The pre-defined analyticalmodel may be received in the form of an analytical model code bundle andmay include pre-computed coefficients. The pre-defined analytical modelmay be verified (discussed below) and stored in model storage database106. In certain embodiments, the pre-defined analytical model may onlybe stored upon verification, while in other embodiments, the pre-definedanalytical model may be stored even upon failing a verification.

The user interface circuitry 114 may be configured to accept adesignation input specifying training data with which to train theanalytical model (612). For example, the analytical model control userinterface may receive from the user a designation of an address orlocation of stored training data, which may exist on the historical datastorage database 122, the hard drive 238, the solid-state drive 240, thedata center 218, or another database 224 or 226. Alternatively, theanalytical model control user interface may receive a direct upload oftraining data from the user, for example, from a client computer 228 andthrough the networks 216, which may subsequently be stored in any of theabove referenced locations. The analytical model control user interfacemay allow the user to specify partitions of the training data intosegments that can be interchangeably used for training andcross-validation. Alternatively, the machine 100 may automaticallypartition the training data into such segments.

The user interface circuitry 114 may be configured to accept a usertraining input configured to cause training of the analytical model withthe user-designated training data by the model builder circuitry 102 tocreate the trained analytical model (614). The model builder circuity102 may responsively train the analytical model on the compute engine118 and store the trained analytical model in the model storage database106. In one embodiment, the user interface circuitry 114 may causedisplay of an error rate for the trained analytical model to the uservia the analytical model control user interface (e.g., through a GUI).

Once the analytical model is trained, the user interface circuitry 114may be configured to accept a deployment input configured to causedeployment of the trained analytical model on the compute engine 118 bythe model deployment circuitry 104 (616). Similarly, the user interfacecircuitry 114 may be configured to accept a retraction input configuredto cause withdrawal of deployment of the trained analytical model on thecompute engine 118 by the model deployment circuitry 104 (618). Forexample, a user may submit a command via the analytical model controluser interface to deploy or withdraw the trained analytical model on thecompute engine 118.

In some embodiments, a user may have built, trained, configured, orotherwise developed a pre-defined analytical model using a differentplatform, or using the same machine 100 at a previous time. The user mayhave the pre-defined analytical model stored on a client device or at aseparate data store (e.g., database 226, database 224, or data store220). Instead of developing a new analytical model using the modelbuilder circuitry 102, the user may provide the pre-defined model to themachine 100. In certain embodiments, the model builder circuitry 102 isnot included with the machine 100 and the machine 100 instead utilizesuser-supplied pre-defined models.

The pre-defined analytical model may exist in many different forms. Forexample, the pre-defined analytical model may be an analytical modelcode bundle including source code or compiled code for an analyticalmodel which may define the type of analytical model and variousparameters. The pre-defined analytical model may be a .JAR file (JavaArchive file), a .R file (for scripts written in R programminglanguage), a SparkR file (a variation on the .R file), a Scala codefile, an OpenCV code file, a JSON file, an XML file, or other filetypes. The pre-defined analytical model may comprise a manifest ofdirections to produce an executable analytical model. The pre-definedanalytical model can be source code, compiled instructions, or aproprietary file type in each case where the system includes the logicto verify and deploy for processing into the target operationenvironment.

The pre-defined analytical model may require coefficients and/orparameters to be used in the execution of its operations. These valueswill be flagged explicitly at submission time or implicitly throughagreed-upon naming or structural conventions within the submitted file.The submission of these files may occur through an API interface, a UIinterface, a file transfer via upload to a directory, FTP, or SFTP. Theonboarding and mapping of a data storage system that contains thecomponents of the pre-defined analytical models whose interfaces arethen mapped to the system.

FIG. 10 shows a flow diagram of logic 1000 that the machine 100 mayimplement to verify and deploy a pre-defined analytical model. Forinstance, the model deployment circuitry 104 may be configured toimplement some or all of the logic 1000 shown in FIG. 10. After thepre-defined analytical model has been received and stored (discussedwith respect to FIG. 11, below), the model deployment circuitry 104 mayaccess the pre-defined analytical model stored in a memory system (e.g.,model storage database 106) (1002). If coefficients for the pre-definedanalytical model exist or were also uploaded (e.g., were received withthe pre-defined model or otherwise provided to the machine 100) themodel deployment circuitry 104 may also access the coefficients for thepre-defined analytical model stored in the memory system (1002).

The model deployment circuitry 104 may determine a model code type ofthe pre-defined analytical model (1004). For example, the modeldeployment circuitry 104 may determine that a file extension (e.g.,“.JAR”) is associated with a particular model code type (e.g., a JARfile). The model deployment circuitry 104 may analyze the contents ofthe pre-defined analytical model to detect if the model code type isincluded (e.g., in a header) or to detect a pattern or command of thecode bundle corresponding to a pattern or command of a known model codetype. The model deployment circuitry 104 may look at metadata associatedwith the pre-defined analytical model to determine if the model codetype is indicated. As mentioned above, the pre-defined analytical modelmay be source code, compiled code, or proprietary file.

The model deployment circuitry 104 may verify that the pre-definedanalytical model and/or the corresponding coefficients conform topre-determined compatibility requirements applicable to the model codetype (1006). Such pre-determined compatibility requirements may exist inmemory 206 as pre-defined model compatibility requirements 311, shown inFIG. 3. For example, the pre-determined compatibility requirements mayinclude dependency requirements or other requirements dictating ruleswhich the source code or compiled code of the pre-defined analyticalmodel must follow. In one embodiment, verifying may include determiningthat the pre-defined analytical model includes all the necessarydependencies required for the model code type (1008). In anotherembodiment, verifying may include determining that the dependenciesincluded with the pre-defined analytical model do not conflict (1010).Such verification may be specific to particular run time environments(e.g., to ensure that the pre-defined analytical model includes alldependencies required to run on a particular run time environment). Inone example, multiple run time environments may be capable of runningthe pre-defined analytical model (e.g., R on Docker containers or SparkR). The verification can be performed with respect to one, some, or allof those multiple candidate run time environments. The model deploymentcircuitry 104 may store the pre-defined analytical model in modelstorage database 106 only upon successful verification, or,alternatively, may store the pre-defined analytical model in modelstorage database 106 even upon failed verification while possiblyproviding flags or other feedback to the user with respect to a failureto verify.

Dependencies include features such as external libraries (e.g., codeDLLs) that the source code for the pre-defined analytical model dependson to run. The dependencies may be specific to or required by aparticular run time environment. For example, if a pre-definedanalytical model will be implemented using Amazon Web Services™ (AWS), apre-determined requirement may be that the pre-defined analytical modelbe compiled with the AWS API code, which makes the AWS API code librarya dependency. This is because when the machine 100 submits thepre-defined analytical model to the target environment (e.g., AWS), thepre-defined analytical model preferably has the source compiled with alldependencies in order to be executable without further processing by thetarget environment. Two cases may create dependencies failures. Case 1:If some dependencies were not compiled with the source code, then thetarget environment won't be able to execute the pre-defined analyticalmodel. Case 2: Dependencies with nested dependencies having conflictingversions. For example, Source Code→dependency A→dependency X (version0.5); Source Code→dependency B→dependency X (version 1.0). When theSource Code is compiled (e.g., using Apache Maven), the Source Code willbe compiled with the first version it sees. In this case, it willcompile Source Code, dependency A, dependency X (version 0.5), anddependency B (but not dependency (version 1.0) which the compiler maydetermine is duplicative). However dependency B expected version 1.0 fordependency X, and as such, classes, methods, and code associated withdependency B may crash. To detect such dependency failures, the modeldeployment circuitry 104 may use logic stored as part of modeldeployment instructions 310 to review the pre-defined analytical modeland catch Case 1 and/or Case 2, discussed above.

The model deployment circuitry 104 may determine a compatible run timeenvironment for the model code type from among multiple run timeenvironments (1012). For example, based upon the determination of theparticular model code type for the pre-defined analytical model, themodel deployment circuitry 104 may utilize a lookup table or otherdatabase to determine which run time environment or environments maysupport execution of the pre-defined analytical model. For example, ifthe model deployment circuitry 104 determines that the pre-definedanalytical model is R code, the model deployment circuitry 104 may thendetermine that compatible run time environments include a SparkRenvironment, Amazon Web Services™ (AWS) Spark, and/or a dockerized tierof R machines. In another example, if the model deployment circuitry 104determines that the pre-defined analytical model is a JAR file, themodel deployment circuitry 104 may then determine that compatible runtime environments include AWS Spark with Elastic Map Reduce (AWS EMR) ora self-managed cluster of machines running Datastax Cassandra-coupleddeployment of Spark. Many different run time environments are possible,including Statistical Analysis System (SAS®).

If the machine 100 does not have access to a run time environmentassociated with the determined model code type, the model deploymentcircuitry 104 may output an indication to the user that the pre-definedanalytical model is not executable with the currently availableresources. The model deployment circuitry 104 may provide suggestions toenable execution of the pre-defined analytical model, such as a list ofcompatible run time environments and/or compute engines that may run thecompatible run time environments. An example list of compatible run timeenvironments and/or compute engines may be in the form of a lookuptable. The system may create and curate the lookup table by deployingfor execution various code bundles of unknown behavior to verify if therun time environment can support that type of code. For example, themodel deployment circuitry 104 may deploy code bundles on differentversions of run time environments (e.g., Spark 1.3 and Spark 1.4) toverify, on the different version of the same run time environment, thecorrect execution based on previous results.

The model deployment circuitry 104 may deploy the pre-defined analyticalmodel with the set of coefficients through the communication interface208 to a compatible run time environment on the compute engine 118(1014), which may be similar to the process discussed with respect tostep 414 of FIG. 4. In some embodiments, the model deployment circuitry104 may parse the pre-defined analytical model for classpath (e.g.,execution starting point for the code bundle), auxiliary files to addfor execution, and the code bundle name.

FIG. 11 shows a flow diagram of logic 1100 that the machine 100 mayimplement to provide additional functionality with respect to thepre-defined analytical model. For instance, the model deploymentcircuitry 104 may be configured to implement some or all of the logic1100 shown in FIG. 11. The model deployment circuitry 104 may receivethe pre-defined analytical model and/or corresponding coefficients froma client device, for example, via the communication interface 208(1102). A user may utilize a user interface or a command line interfaceto upload the pre-defined analytical model. In one embodiment, the usermay use a GUI 700, discussed below with respect to FIGS. 7-9. Asdiscussed above, the model deployment circuitry 104 may store thepre-defined analytical model in a model storage database 106 or inanother data store (1104). The model deployment circuitry 104 mayreceive API instructions to verify the pre-defined analytical model(e.g., according to step 1006 of FIG. 10) and/or to deploy thepre-defined analytical model (e.g., according to step 1014 of FIG. 10)(1106). Examples of API instructions that may be received by the machine100 are discussed further below. The model deployment circuitry 104 mayconvert the received API instructions into command-line arguments for anAPI of the compatible run time environment (1108). For example, themodel deployment circuitry 104 may include a lookup table or otherdatabase of received commands which it is programmed to respond toaccording to the API 110 that correspond to the possible command-linearguments to be provided to the compatible run time environment.

The model deployment circuitry 104 may provide a status of thepre-defined analytical model via the interface, for example, to a userdevice (1110). The status may be provided upon request or automaticallyby default. The status may include, for example, whether the pre-definedanalytical model is presently running, whether the pre-definedanalytical model is presently deployed, how frequently it is running,how long it takes to execute, whether a data store (e.g., for results orsource data) is unavailable, whether the pre-defined analytical modelstopped, whether the pre-defined analytical model failed, as well asother useful status indicators. These statuses may be written to a logfile or table (e.g., stored in results storage database 108) or providedto the user via a command-line interface or via a GUI 700, discussedbelow with respect to FIG. 7-9.

The model deployment circuitry 104 may receive an execution schedule forthe pre-defined analytical model via the communication interface 208from a client device (1112). For example, the schedule may dictate afrequency at which the pre-defined analytical model is to be executed(e.g., every 10 minutes, once a day, once a quarter, upon receipt of newdata). The execution schedule may be received as a file, a value, an APIcommand, or may be entered via a GUI 700, discussed below with respectto FIG. 7-9. The model deployment circuitry 104 may deploy and executethe pre-defined analytical model according to the execution schedule(1114). This may entail the model deployment circuitry 104 initiatingindividual commands to the compute engine 118 to run the pre-definedanalytical model according to the execution schedule, or setting aschedule for execution that is subsequently managed by the computeengine 118.

The model deployment circuitry 104 may monitor an output log, which maybe a file in a file system or a table in a database storage system,updated by the compatible run time environment (1116). The output logfile may be stored in the results storage database 108. For example, themodel deployment circuitry 104 may extract an application identifier anda corresponding status from the output log file as the pre-definedanalytical model executes on the run time environment. The modeldeployment circuitry 104 may further relay the results to a user uponrequest or automatically upon updating of the results. The applicationidentifier and status extracted from the output log file may be providedto the user.

The model deployment circuitry 104 may monitor multiple trainedpre-defined analytical models and automatically select the best model todeploy. For example, the model deployment circuitry 104 may compare afirst error rate of the pre-defined analytical model deployed on thecompatible run time environment with a second error rate of a secondpre-defined analytical model (1118). The second pre-defined analyticalmodel may be currently deployed or may have been deployed previously.The error rate may indicate the accuracy of the analytical model, andmay comprise, for example, a RMS error, an F1 score, a standarddeviation, or another error rate indicator. The model deploymentcircuitry 104 may determine, for example, that the second error rate islower than the first rate and may, as a result, undeploy the firstpre-defined analytical model and instead deploy the second pre-definedanalytical model (1120). This is because, in this example, the errorrates indicate that the second pre-defined analytical model (e.g.,including the trained coefficients) is more accurate.

In accordance with these various methods and logic flow diagrams, themachine 100, and in particular, the model deployment circuitry 104,provides an abstraction layer for the management of analytical modelsaway from the particular requirements of the target run timeenvironments and/or compute engines 118. Thus, for example, the machine100 may utilize a single interface to manage and deploy differentanalytical models across different run time environments. For example,FIG. 12 shows a flow diagram of logic 1200 that the machine 100 mayimplement to decouple the management of analytical models from targetrun time environments. For instance, the model deployment circuitry 104may be configured to implement some or all of the logic 1200 shown inFIG. 12. The model deployment circuitry 104 may access a firstpre-defined analytical model and first coefficients from the memorysystem (1202). The model deployment circuitry 104 may determine a firstmodel code type of the first pre-defined analytical model (1204) anddetermine a first compatible run time environment for the first modelcode type from among multiple available run time environments (1206).Similarly, the model deployment circuitry 104 may access a secondpre-defined analytical model and second coefficients from the memorysystem (1208). The model deployment circuitry 104 may then determine asecond model code type of the second pre-defined analytical model thatis different from the first model code type (1210). The model deploymentcircuitry 104 may also determine a second compatible run timeenvironment for the second model code type from among the multipleavailable run time environments, the second compatible run timeenvironment being different from the first compatible run timeenvironment (1212). The model deployment circuitry 104 may deploy thefirst pre-defined analytical model with the first coefficients throughthe communication interface 208 to the first compatible run timeenvironment on the compute engine 118 (1214) and deploy the secondpre-defined analytical model with the second coefficients through thecommunication interface 208 to the second compatible run timeenvironment on the compute engine 118 (1216). Thus, though theanalytical models and run time environments are disparate, the user isprovided with a single tool and interface with which to manage anddeploy the multiple varying analytical models.

FIGS. 7-9 provide an example GUI 700 implemented as the analytical modelcontrol user interface. The example GUI 700 may be dynamicallyreconfigurable such that it can be reconfigured to be provided anddisplayed on a variety of different display platforms, display sizes, ordisplay configurations. For example, the GUI 700 may be reconfigured toappear different when viewed on a client mobile device 230 versus aclient computer 228. User interface instructions 322 stored in memory206 may include logic, instructions, and data to implement the exampleGUI 700 or another GUI.

The GUI 700 may be generated by the processors 204 or other circuitryand provided via the communication interface 208 to a client device.During implementation of the GUI, the processors 204 may receive GUIelements (e.g., from memory 206 or elsewhere), GUI events, and GUIinputs (from various sources as discussed herein), and responsivelygenerating the GUI 700. For example, the processors 204 may receive dataor calculate data corresponding to an analytical model and may, in turn,update or otherwise change a display of data corresponding to thatanalytical model within the GUI 700.

The example GUI 700 may include a dashboard 702 that providesinformation about a user 704, an event stream 706, e.g., to providerecent action updates, and a navigation panel 708 to enable navigationbetween different features or screens of the GUI 700. The GUI 700 mayinclude a main working pane 710, and in some embodiments, can beswitched between displaying models 712 (as is shown in FIGS. 7-9) orresults 714 (e.g., predictive results of deployed analytical models). Inthis example, the GUI 700 shows a first analytical model(“Classification Model A”) 716 and a second analytical model(“Classification Model B”) 718. Data corresponding to each analyticalmodel 716, 718 may be displayed, which data may be collected from modelmetadata 328 stored in model metadata storage database 112. For example,a name 720, a creation date 722, an error rate 724, a predicted valueoutput 726, input variables 728, and configuration parameters 730 may beshown. Other data not shown here may include an analytical modelalgorithm type, model storage location, or other model metadatadiscussed herein.

The GUI 700 may also provide a current status of the particularanalytical model. For example, the first analytical model 716 is shownas presently deployed via status indicator 732, while the secondanalytical model 718 is shown as trained (though not deployed) viastatus indicator 734. A dynamic command button may be provided toperform various functions on or with the analytical model (e.g., toperform a next logical function in the lifecycle of an analyticalmodel). For example, command button 736 provides the user with an optionto un-deploy the first analytical model 716, which is currently deployed(e.g., corresponding to logic 618). Similarly, command button 738provides the user with an option to deploy the second analytical model718, which is currently trained but not deployed (e.g., corresponding tologic 616).

The GUI 700 may also provide an actions interface 740 that may includeone or more possible actions to a user. A user may be able to select anaction of creating a new analytical model by selecting the button“Create New Model” 742 (e.g., corresponding to logic 604). Turning toFIG. 8, upon selecting the button 742 to create a new analytical model,an interface 802 to add a new model may appear as a pop-up screen orother graphical interface component, providing the user with the abilityto add and configure the new analytical model. The interface 802 mayinclude user-updatable fields, for example, to provide a name 804, adescription 806, a selection of an output variable 808 (e.g., “labelvariables”), a selection of input variables 810 (e.g., corresponding tologic 608), a selection of an analytical model algorithm type 812 (e.g.,“approach template”) (e.g., corresponding to logic 606), and aninterface to enable alteration of one or more configuration parameters814 (e.g., “attributes”) (e.g., corresponding to logic 610) for the newanalytical model. The user may type, select, or otherwise provide theinputs to the fields shown.

In certain embodiments, a user may be able to upload a pre-definedanalytical model, for example in the form of an analytical model codebundle. This may be performed in addition to or instead of theanalytical model creation steps discussed above. The GUI 700 may providean interface element that allows a user to upload their own pre-definedanalytical model. For example, upon selection of the button 743 (“UploadNew Model”), an interface may appear allowing a user to select ordrag-and-drop one or more files of the pre-defined analytical model foruploading to the system. The machine 100 may verify that the pre-definedanalytical model is correct and/or adheres to pre-determinedrequirements. Upon verification, the GUI 700 may show the uploadedanalytical model in the main working pane 710 or elsewhere. However, ifthe pre-defined analytical model fails verification, one or more errorsor issues may be flagged or otherwise presented to the user via the GUI700.

After the user is finished with adding the new model via the interface802, the interface 802 may be removed and the main working pane 710 maynow show the newly created analytical model 902. The new analyticalmodel 902 may show much of the same data fields shown for the firstanalytical model 716 and the second analytical model 718, though somedata fields may be empty or omitted for lack of data. For example, priorto being trained, the new analytical model 902 may not have a calculatederror rate and therefore the error rate may not be displayed. The newanalytical model 902 may include a dynamic status indicator 904 showingthat the new analytical model 902 is ready to be trained. Further, thenew analytical model 902 may also include a dynamic command button 906providing the user with an option to train the new analytical model 902(e.g., corresponding to logic 614).

The GUI 700 may provide other functionality not expressly shown here.For example, the GUI 700 may provide an interface to set up processingpipelines by specifying a target results storage database 108 forstorage of the results. The GUI 700 may also provide an interface tolist or catalog existing analytical models, possibly organized withinrelated projects or collections. The GUI 700 may provide an interface tolookup status of jobs in progress or that have completed including anyassociated success or error messages. Performance specifications (e.g.,error rates) may be displayed allowing users to compare the accuracy ofvarious configurations of different analytical models.

CODE EXAMPLES

The following are examples illustrating and explaining various featuresdiscussed above.

Below is sample code that demonstrates how a code bundle trains amachine learning model. In the illustrated example, a linear regressionmodel is trained having an equation similar to ax+by=d, where a and bare the coefficients that are being determined (e.g., via training).Inputs x and y may correspond to the relevant inputs used for theparticular analytical model (e.g., temperature and date, etc.). Theoutput d is the predicted output. In the example below, the arrows (“→”)indicate lines where we are determining the coefficients by training themodel, printing those coefficients (weights), and saving the results.

public Object trainModelAndSaveResults( ) {  SparkConf sparkConf = newSparkConf( ).setAppName(appName);  JavaSparkContext jsc = newJavaSparkContext(sparkConf);  // Set AWS keys  jsc.hadoopConfiguration().set(″fs.s3n.impl″,  ″org.apache.hadoop.fs.s3native.NativeS3FileSystem″); jsc.hadoopConfiguration( ).set(″fs.s3n.awsAccessKeyId″, accessKey); jsc.hadoopConfiguration( ).set(″fs.s3n.awsSecretAccessKey″, secretKey); // Load the training data from S3  JavaRDD<Row> trainingData =filterInputCSVFile(jsc, ″s3n://″ + s3BucketName + ″/″ + inputFile,outputVariable, inputVariables);  // Parse the data points JavaRDD<LabeledPoint> parsedData = trainingData.map(new ParseRow( )); // Normalize the data points for linear regression JavaRDD<LabeledPoint> normalizedData = parsedData.map(newNormalizePoint( )).cache( );  // Train the linear regression model(ax+by)  // -> This is where the coefficients of the model are trained;for example, a and b for ax+by  final LinearRegressionModel model =LinearRegressionWithSGD.train(JavaRDD.toRDD(normalizedData),modelPara.getNumIter( ));  // -> Print the coefficients a and b forax+by  System.out.println(″Linear regression model weights:\n″ +model.weights( ));  // Evaluate model on training examples and computetraining error  JavaRDD<Tuple2<Double, Double>> valuesAndPreds =normalizedData.map(new LinearRegressionPredictPoint(model));  double MSE= new JavaDoubleRDD(valuesAndPreds.map(new SquareDistance( )).rdd()).mean( );  System.out.println(″Training Mean Squared Error = ″ + MSE); /* -> Save results to target database... Code removed for simplicity */ return model; }

In accordance with the disclosed processes and structures, the machine100, and in particular, the model builder circuitry 105 and the modeldeployment circuity 104, provide a level of abstraction to a user forthe development, testing, deployment, and management of analyticalmodels. This layer of abstraction lowers the initial time burden,resource burden, and software engineering knowhow required to developand test analytical models. Further, the methods and structure describedherein provide for “lightweight” analytical model development, training,and deployment as the abstraction layer on top of the models exposes awide range of possible analytical approaches, which are easilyconfigurable and trained on-demand. Such lightweight model developmentand training can allow for quick iterations, allowing a user toiteratively adjust the parameters of the analytical model and re-testduring the process of creating an accurate analytical model for aparticular application or dataset. This enables a domain expert withoutextensive data science and data engineering backgrounds or understandingto easily create and iteratively develop and deploy an accurate datamodel. Once the analytical model has been trained and stored, it can beeasily deployed against a stream of incoming data or a batch of data.Predictions are stored in the results storage database 108 as the datais processed and are readily made available for viewing and furtherprocessing.

The methods, devices, processing, circuitry, structures, architectures,and logic described above may be implemented in many different ways andin many different combinations of hardware and software. For example,all or parts of the implementations may be circuitry that includes aninstruction processor, such as a Central Processing Unit (CPU),microcontroller, or a microprocessor; or as an Application SpecificIntegrated Circuit (ASIC), Programmable Logic Device (PLD), or FieldProgrammable Gate Array (FPGA); or as circuitry that includes discretelogic or other circuit components, including analog circuit components,digital circuit components or both; or any combination thereof. Thecircuitry may include discrete interconnected hardware components or maybe combined on a single integrated circuit die, distributed amongmultiple integrated circuit dies, or implemented in a Multiple ChipModule (MCM) of multiple integrated circuit dies in a common package, asexamples.

Accordingly, the circuitry may store or access instructions forexecution, or may implement its functionality in hardware alone. Theinstructions may be stored in a tangible storage medium that is otherthan a transitory signal, such as a flash memory, a Random Access Memory(RAM), a Read Only Memory (ROM), an Erasable Programmable Read OnlyMemory (EPROM); or on a magnetic or optical disc, such as a Compact DiscRead Only Memory (CDROM), Hard Disk Drive (HDD), or other magnetic oroptical disk; or in or on another machine-readable medium. A product,such as a computer program product, may include a storage medium andinstructions stored in or on the medium, and the instructions whenexecuted by the circuitry in a device may cause the device to implementany of the processing described above or illustrated in the drawings.

The implementations may be distributed. For instance, the circuitry mayinclude multiple distinct system components, such as multiple processorsand memories, and may span multiple distributed processing systems.Parameters, databases, and other data structures may be separatelystored and managed, may be incorporated into a single memory ordatabase, may be logically and physically organized in many differentways, and may be implemented in many different ways. Exampleimplementations include linked lists, program variables, hash tables,arrays, records (e.g., database records), objects, and implicit storagemechanisms. Instructions may form parts (e.g., subroutines or other codesections) of a single program, may form multiple separate programs, maybe distributed across multiple memories and processors, and may beimplemented in many different ways. Example implementations includestand-alone programs, and as part of a library, such as a shared librarylike a Dynamic Link Library (DLL). The library, for example, may containshared data and one or more shared programs that include instructionsthat perform any of the processing described above or illustrated in thedrawings, when executed by the circuitry.

Various implementations have been specifically described. However, manyother implementations are also possible.
